Oakland A's call up Max Muncy & Jesse Hahn, put Josh Phegley on DL, option Eric Surkamp

The Oakland A's officially announced several roster moves on Tuesday. RHP Jesse Hahn and 1B/3B/LF Max Muncy were called up from the Triple-A Nashville Sounds, catcher Josh Phegley was placed on the disabled list, and LHP Eric Surkamp was optioned to Triple-A. Most of these moves were first announced by manager Bob Melvin after Monday night's game, but now they are official. The only move that remained in question until now was Muncy's promotion.

The 25-year-old Muncy made his MLB debut in 2015 but has not yet played in the bigs this season. His numbers were uninspiring last year, but he has rebounded in 2016 by regaining both the power and the plate discipline he had previously showed at lower levels of the minors. He currently carries a batting line of .279/.399/.459, with six homers, 22 BB, and 28 Ks, and his 138 wRC+ leads the Sounds.

Muncy has played mostly 1B and 3B in his pro career, but this season he has primarily played LF in a Nashville lineup that is packed with corner infielders. His defense itself is only decent, but his growing versatility is becoming a plus for a team that highly values multi-positional ability. He is more mobile than he might seem from his appearance, and I was generally impressed with his work at 1B during his big league trial last year. For more on Muncy, check out our post from May 11 in which we advocated for his promotion upon the next Oakland position player injury (though it turned out to be Phegley going down, instead of Valencia re-aggravating his hamstring).

Hahn will start on Tuesday against the Texas Rangers. His promotion is made possible by Phegley going on the DL, since Hahn had not yet spent the minimum 10 days on his latest optional assignment in the minors. This will be his third MLB start of the season, and in his first two games he produced a line of 12 ip, 4 ER, 4 Ks, and 6 BB. Surkamp had previously been scheduled to start Tuesday but will now rejoin Nashville's rotation until he is next needed in Oakland.

With Phegley on the DL, Matt McBride will continue to serve as the second catcher behind Stephen Vogt. McBride received positive reviews after starting Monday's game behind the plate, in which he caught Sean Manaea's first MLB win.

Looking further down in the minors, 1B/3B Ryon Healy was promoted from Double-A Midland to replace Muncy in Triple-A. Healy's 1.036 OPS ranked second among all qualified hitters in the Texas League, and fourth among all hitters with at least 100 PAs. Meanwhile, outfielder Tyler Marincov was promoted from Single-A Stockton to Double-A to replace Healy. Marincov's nine home runs ranked second in the Cal League. Both players are 24 years old, and in fact Marincov is three months older than Healy.
